OS 10.4 - Accounts icon missing from System Preferences

Hi there, I'm new to Macs and have recently taken over a Powerbook G4 at work. For some reason, the Accounts/Users icon is missing when I pull up System Preferences, even when I login as root. Is there a setting I need to look into to re-show the Accounts icon in the System Preferences menu? Thanks in advance!
